研究了磁记忆检测技术在铁道机车承力部件上的应用,在对铁道机车车辆的辐板孔进行了磁记忆检测后,用磁粉检测进行了复检。结果表明,磁记忆技术可以有效发现表面裂纹等缺陷,并且能对铁道车辆车轮辐板孔产生破坏的可能性进行预测。
The application of magnetic memory testing technology on bearing components of railway locomotives was studied. After magnetic memory testing of spoke plate holes of railway locomotives, the magnetic particle inspection was used for re-inspection. The results show that the magnetic memory technology can effectively detect defects such as surface cracks, and can predict the possibility of damage to the wheel spoke plate hole of railway vehicles.
